Claims priority, application Germany May 7, 1953 4 Claims. (Cl. 285-30)This invention relates to the design and the connection of devices whichare traversed by a flowing gas and' for this purpose are tted to asupply and draw-ol pipe. Such devices are, for instance gas meters,water meters, regulating devices, filters, stop valves and the like.

Such devices hereinafter shortly referred to as uid handling devices orgas handling devices have hitherto been provided with separate inlet andoutlet sockets and have been connected to the supply and ow-ol` pipe bymeans of intermediate pipe pieces, pipe elbows or the like.` Owing toinexact distances with such connections there arise undesired pipe linestresses and tensile forces on the connected devices when installingthem. In many cases also it is necessary to intersect such connectingpieces, for instance, if the inlet socket has been provided on the leftside of the connected device and occasionally the supply pipe has beeninstalled on the right side.

When using intermediate pieces and pipe elbows for Y The invention hasfor its object to simplify essentially the installation of fluidhandling devices and to reduce largely the costs of the plant, and inparticular to insure a connection being free from stresses whileemploying as few sealing points as possible.

It is another Object of the invention to avoid intersecting pipeconnections and to make the plant independent of the occasional positionof the connecting pipes. Furthermore, the invention provides thepossibility of connecting by means of one joint adapter piece severalfluid handling devices, e.g., a stop valve, a regulating device and ameter to the inlet and outlet line.

It is a further object of the invention to provide tapping pointscapable of being closed at the adapter piece in order to make itpossible to connect control devices in parallel to the uid handlingdevice, without pipe lines or the connected devices themselves beingprovided with such tapping points.

Substantially the present invention contemplates an adapter piececonnected to the inlet and outlet line, with inlet and outlet channelsbeing arranged concentrically one in the other in a device mountedconnection socket, the adapter piece having corresponding concentricopenings and being rigidly connected with the uid handling device at theconnection socket.

For a fuller understanding of the nature of the invention and itsapplication with dilerent lluid handling devices, reference should behad to the following detailed description taken in connection with theaccompanying drawings wherein several preferred embodiments of theinvention are shown by way of illustration and not by way of limitation.

In the drawings:

Fig. l shows in schematical representation a fluid handling device beingin rigid connection with a simple pipe line adapter piece.

Fig. 2 represents in sectional View a lluid handling device being inrigid connection with pipe line adapter piece of somewhat differentdesign.

States Patent rice Figs. 6, 7 and 8 show particular parts which will bedescribed later.

In Fig. 1 the numeral 1 designates a device being traversed by a flowingmedium and having a snout joining socket 2. Inside of the joining socket2 a further joining socket 3 has been arranged concentrically to theirst one. The joining socket 2 is in open connection with the interiorspace 4 of the device 1, while the joining socket 3 is connected with atube 5 being arranged inside the device 1. The flowing medium streamsinto the device 1 through the annular space 6 being formed between thetwo joining sockets 2 and 3, enters the space 4 and leaves the deviceagain through the tube 5 and the joiningsocket 3. Thus the inlet andOutlet openings are arranged concentrically to one another.

A device 1 being designed in such manner will be connected to a supplypipe and a tlow-ot pipe by means of a pipe line adapter piece 7.` Aninlet channel 8 and an outlet channel 9 are arranged in this manner inthis pipe line adapter piece 7 so that on the one hand the two channelsfall concentrically into a side-branch joint socketv 10 and on the otherhand into separate ljoining sockets 11, 12. The joining sockets 11 and12 may be connected directly to the respective outlet and inlet pipes(not here shown) or indirectly through the intermediation of pipe elbows13, 13 respectively. Also the adapter piece 7 may be designed this waythat the pipe elbows 13, 13 are cast in one piece with it. The jointsocket 10 is fitted with an external thread 14 on which a ring nut 14being supported by the joining socket 2 of the device 1 has been screwedon. Thereby, with any desired twisting in relation to the adapter piece7, it is possible to connect the device 1 with it by screwing, withoutsuch` twisting inuencing in any way the connection of the concentricallyarranged channels 8, 9 with the corresponding channels of the device 1.Simultaneous sealing of the two channels 8 and 9 is accomplished bymeans of a packing disk 15, as represented separately in Fig. 3.

This packing disk consists of an inner packing ring 16` for sealing thechannel 9 and the inner joining socket 3, and an outer packing ring 17lying intermediate the outer joining sockets 2 and 10. Both packingrings 16 and 17 are connected with one another by means of bridges 18.

A pipe line adapter piece 7 fundamentally of the same.v

as shown in Fig. 1.

By releasing the ring nut 14' the device 1 can easily be disconnected,e.g., for the purpose of repair work that may become necessary, whilethe pipe line adapter piece 7 or 7 may remain rigidly mounted ascomponent part of the pipe line system. With device 1 being removedp thejoining socket 10 of the pipe line adapter piece 7 or 7'. may be lockedby means of a sealing cap 21 (shown in Fig. 7) that locks simultaneouslyboth channels 8 and` 9 by means of a packing disk 22, so that the ow ofthl Patented Apr. 7, 1959I Also, in the pipe line Naturally, suchtapping holes may of course also rbe provided with the pipe line adapterpiece,

medium is interrupted. In case further flow of the medium is desiredwhen the device has been removed, an overow cap 23 (Fig. S) may be used,which although sealing the joining socket 10- toward outside by means ofa packing ring 24, nevertheless provides junction between the channels 8and 9 through the space 25. The caps 21 and 23 will -be screwed on thethread 14 of the joining socket 10.

A gas meter 26 has been represented in Fig. 4. Since its manner ofoperation is known in itself, it does not need to be explained here. Incontrast to known gas meters having separately arranged inlet andoutletsockets,` with this gas meter 26 inlet and outlet sockets 27, 28, in themanner as previously has been described, are provided coaxially one inthe other. The gasv owing through the annular space 29 into the gasmeter 26 will, after having passed the measuring chambers 30, be carriedot through the tube 3l which is connected with the inner outlet socket28.. In Fig. 4 furthermore there has been represented a gas pressureregulator 33 which manner of operation as well is known and does notconstitute a part of the invention. In contrast to known regulators alsoin this case the inlet opening 34, as previously has been described, isarranged coaxially in relation to the outlet opening. The regulator 33is connected with the gas meter 26 by means of joint pipe line adapterpiece 36. In addition the pipe line adapter piece 3'6 carries a stopvalve 37 of the type as represented in Fig. with inlet and outletsockets 38, 39 being arranged coaxially one in the other. According tothis, the pipe line adapter piece has three joining sockets 40, 41, 42with channels 46, 43, 43, 44', 44, 45 lying concentrically one in eachother which are in communication accordingly with the inlet and outletsockets of the devices 26, 33, 37.

If one assumes the stop valve 37', as shown in Fig. 5, to be connectedto the pipe line adapter piece 36 of Fig. 4, then the medium iiows froma not represented' supply pipe through the joining socket 47 into thechannel 46, passes the Istop valve 37 and leaves it through the channel43. Then the medium enters the regulator 33 through the channel 43 andleaves it in the channel 44 in order to enter the gas meter 26 throughthe channel 44 and finally through the channel. 45 and the joiningsocket 48 to reach the there attached flow-ofi conduit.

Therefore, by the concentric arrangement of the inlets and outlets atthe devices, it is possible to use one single jo-int pipe line adapterpiece 36 for connection of several devices (26, 33, 37) and to realize asimple, nonexpensive and clear installation. The interior channels 45and 43 of the pipe line adapter piece 36 are provided with clcsabletapping holes 57, 58 thus, as already has pre-y viously been described,making possible to connect measuring or testing devices temporarily tothe tapping points. Since, however, the tapping holes S7, 5S have topenetrate the outer channel 44 or 44', a rib 59, as represented in Fig.6, has been provided intermediate the inner and the outer wall of thechannel in order to conduct the tapping holes toward outside.

In Figure 5 the installation of the previously described stop valve 37has been represented in connection with a water ilow meter 49 -being aswell provided with coaxial inlet and outlet openings 50, 51. The jointpipe line adapter piece 52 as has been employed here has two side `byside arranged joining sockets 42, S3 with channels 46, 43'; 46', 54lying concentrically one in the other and being designed in this mannerthat the outer channel 46 of the one joining socket 42 communicates withthe inner channel 46 of the second joining socket 53, while the twoother channels 43', 54 lead to each one pipe joining socket 55, 56assigned to the supply and flow-off pipes respectively.

The present invention is not limited to the preferred embodiments ashave been represented and described hereinabove, but relates also to thedesign and the connection of other connected devices, such as pumps,

4. blowers and the like accordingly. It is immaterial for the nature ofthe invention which of the joining sockets lbeing arrangedconcentrically one in the other is used as inlet and which is used asexit for the flowing medium. Fastening of the connected devices to pipeline adapter piece neednotto be done by meansofacap nut.. Flanged screwfastenings or ralso bolt locks (bayonet catches) may be used. p
